HighPoint RocketStor 6661A-2USB Thunderbolt 3 to 2x 10Gb/s USB 3.1 Adapter is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Completely reasonable TB3 PCIe Chassis I bought this product because I needed a PCIe chassis for a Blackmagic DeckLink card, and a USB3.1 card for another use. I figured I could pop the USB card out of the chassis and install the DeckLink card, and I was absolutely right. The chassis tolerance is a bit off (if you're not careful, you could probably snap the PCB installing the card) but once it's installed it's robust and secure. Note that it only supplies around 25W of power to the card, so this may not be suitable for more power-hungry equipment. For the DeckLink card, however - it works fantastic. The USB card is also completely fine - works well under MacOS and CentOS, and I succesfully maxed out both ports simultaneously writing to a USB3.1 SSD array.

With this device do I need to have a thunderbolt connection

Hi I have a laptop I want more storage but my laptop dos not have a thunderbolt connection do I need to buy a upgrade my laptop with a thunderbolt card that I would have to put in to my laptop and install to upgrade before I spend money on this device or is it all parts of the device the device you are selling soon may have other ways to connect but I want thunderbolt connection
Asked by: Bedders
Yes, you will need a computer that has a Thunderbolt 3-compatible USB-C port. As I understand it, there are no laptop-compatible TB3 upgrade solutions on the market, so you will need to upgrade your laptop.
